Abstract (en)

[origin: EP2568172A2] A reciprocating compressor comprises a cylinder having a cylinder side gas flow path for guiding refrigerant discharged to the discharge space to an inner circumferential surface of the cylinder and a piston having a piston side gas flow path communicating with the cylinder side gas flow path to distribute and supply the refrigerant guided through the cylinder side gas flow path between the cylinder and the piston. Also, an outlet of the gas flow path is formed in the piston and an inlet of the gas flow path is formed in the cylinder.
